Gastromyzon sp. Blue Zebra Borneo – Blue Zebra Hillstream Loach

Gastromyzon sp. Blue Zebra Borneo is a stunning and rare hillstream loach originating from the fast-flowing rivers of Borneo, Malaysia. This species is highly admired for its distinctive blue zebra-like stripes across its flattened body, giving it a striking and exotic appearance in the aquarium.

Adapted to life in mountain streams with strong currents, this loach has a flattened body and specially adapted fins that act like suction cups, allowing it to cling to rocks and glass surfaces even in fast-moving water. Because of this unique adaptation, Gastromyzon species are often called “butterfly loaches” or “sucker loaches.”

Gastromyzon sp. Blue Zebra Borneo is a peaceful bottom-dwelling fish that spends most of its time grazing on algae, biofilm, and microorganisms found on rocks, plants, and aquarium surfaces. Their fascinating behavior and unique body shape make them a favorite among aquascapers who maintain river-style or high-flow aquariums.
